Removal of homonymy between Haliclona (Haliclona) violacea (Keller, 1883) and Haliclona (Gellius) violacea (De Laubenfels, 1950).
1. Lessepsia violacea Keller, 1883: 19 (type locality Suez, Red Sea). Originally described as Lessepsia violacea Keller, 1883 this species was transferred to Haliclona (Haliclona) by De Weerdt (2002: 866). Reassignment to Haliclona (Haliclona) was based on the description of Keller (1883), because the holotype could not be found in ZMB. Despite the lack of a type specimen, the description of Keller is sufficiently clear to recognize its affiliation and specific distinctness. It is a senior secondary homonym of H. violacea (De Laubenfels, 1950) (ICZN Art. 57.3 & 57.4).
2. Toxadocia violacea De Laubenfels, 1950: 16 (type locality Oahu, Hawaii). Originally described as Toxadocia violacea De Laubenfels, 1950 this species was transferred to Haliclona (Gellius) violacea by Van Soest et al. (2011: 31) based on examination of material from Clipperton Island, Central Pacific, collected by the ‘Presidential Cruise 1938 of Franklin D. Roosevelt’, misidentified by De Laubenfels (1939:
1) as the toxa-lacking Californian species Haliclona enamela De Laubenfels, 1930: 28. De Laubenfels’ material of Hawaii, Clipperton and California of the mentioned species was re-examined by Van Soest et al. (2011). The genus Toxadocia was reassigned to the synonymy of Haliclona (Reniera) Schmidt, 1862: 72 in De Weerdt (2002: 867), but the present species is judged to be better placed in Haliclona (Gellius) Gray, 1867: 538. Regardless of subgenus assignment De Laubenfels’ species name violacea constitutes a homonym with Keller’s species name (ICZN Art. 57.4).
3. Summary: Haliclona (Haliclona) violacea (Keller, 1883) is to be maintained as senior secondary homonym (ICZN Art. 57.3 & 57.4). Haliclona (Gellius) violacea (De Laubenfels, 1950) is a junior secondary homonym and required a new name (ICZN Art. 59.1 & 60.3), for which Haliclona (Gellius) laubenfelsi nom. nov. was proposed, named after Max W. De Laubenfels. [details]
